Obsessive-compulsive disorder (OCD) in children and adolescents is associated with impaired education and worse general health later in life. Access to specialist treatment is often limited. According to a study from Centre for Psychiatry Research at Karolinska Institutet in Sweden and Region Stockholm, internet-delivered cognitive behavioural therapy (CBT) can be as effective … [Read more...] about Online therapy effective against OCD symptoms in the young

You enter a room and quickly scan the crowd to gain a sense of who's there -- how many men versus women. How reliable is your estimate? Not very, according to new research from Duke University. In an experimental study, researchers found that participants consistently erred in estimating the proportion of men and women in a group. And participants erred in a particular way: … [Read more...] about Focus on outliers creates flawed snap judgments: Our quick scan of a crowd isn’t as reliable as we think, new research suggests

Researchers at North Carolina State University have made what is believed to be the smallest state-of-the-art RFID chip, which should drive down the cost of RFID tags. In addition, the chip's design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies. "As far as we can tell, it's the … [Read more...] about Smaller chips open door to new RFID applications

Leipzig/Jena/Ilmenau. Mobile apps like Flora Incognita that allow automated identification of wild plants cannot only identify plant species, but also uncover large scale ecological patterns. These patterns are surprisingly similar to the ones derived from long-term inventory data of the German flora, even though they have been acquired over much shorter time periods and are … [Read more...] about How smartphones can help detect ecological change: Plant occurrence data collected with an app uncovers macroecological patterns in Germany

From the branching pattern of leaf veins to the variety of interconnected pathways that spread the coronavirus, nature thrives on networks -- grids that link the different components of complex systems. Networks underlie such real-life problems as determining the most efficient route for a trucking company to deliver life-saving drugs and calculating the smallest number of … [Read more...] about Novel circuitry solves a myriad of computationally intensive problems with minimum energy

Widely used to monitor and map biological signals, to support and enhance physiological functions, and to treat diseases, implantable medical devices are transforming healthcare and improving the quality of life for millions of people. Researchers are increasingly interested in designing wireless, miniaturized implantable medical devices for in vivo and in situ physiological … [Read more...] about Tiny, wireless, injectable chips use ultrasound to monitor body processes

Touchscreens are notoriously difficult to type on. Since we can't feel the keys, we rely on the sense of sight to move our fingers to the right places and check for errors, a combination of efforts we can't pull off at the same time. To really understand how people type on touchscreens, researchers at Aalto University and the Finnish Center for Artificial Intelligence (FCAI) … [Read more...] about AI learns to type on a phone like humans

The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity. A team led by University of Michigan researchers has developed a material that's at least twice as "magnetostrictive" and far less costly than other materials in its class. In addition to computing, it … [Read more...] about Harnessing the hum of fluorescent lights for more efficient computing

AdaptiFont has recently been presented at CHI, the leading Conference on Human Factors in Computing. Language is without doubt the most pervasive medium for exchanging knowledge between humans. However, spoken language or abstract text need to be made visible in order to be read, be it in print or on screen. How does the way a text looks affect its readability, that is, how it … [Read more...] about Interactive typeface for digital text: Scientists develop adaptive font that speeds up reading

Simon Fraser University researchers have designed a remarkably fast engine that taps into a new kind of fuel -- information. The development of this engine, which converts the random jiggling of a microscopic particle into stored energy, is outlined in research published this week in the Proceedings of the National Academy of Sciences (PNAS) and could lead to significant … [Read more...] about Engine converts random jiggling of microscopic particle into stored energy
